Also, will want to run Nvidia CUDA 8 for packages for RHEL. I have a vote that this should be OK. Any other gotchas?
unsure how / where would you get the cuda stack from ?
Nvidia has links for the ppc64le RHEL7 RPM[1] and the installation instructions on their website[2].
Unfortunately the downloads page doesn't provide the ppc64le "rpm (network)" package (which contains the cuda yum repo config file), however the repo is still available[3].
